Active transport

Question 1

active transport

Answer 1

Active transport moves substances from a more dilute solution to a
more concentrated solution (against a concentration gradient). This
requires energy from respiration

Question 2

How do plants use active transport

Answer 2

Active transport allows mineral ions to be absorbed into plant root
hairs from very dilute solutions in the soil. Plants require ions for
healthy growth.

Question 2

How do plants use active transport

Answer 2

Active transport allows mineral ions to be absorbed into plant root
hairs from very dilute solutions in the soil. Plants require ions for
healthy growth.

Question 3

How do humans use active transport

Answer 3

It also allows sugar molecules to be absorbed from lower
concentrations in the gut into the blood which has a higher sugar
concentration. Sugar molecules are used for cell respiration.
